Arusianus Messius, or Messus, Latin grammarian, flourished in the 4th century.
Life
He was the author of a small extant work Exempla Elocutionum, dedicated to Olybrius and Probinus, consuls for the year 395. It contains an alphabetical list, chiefly of verbs admitting more than one construction, with examples from each of the four writers, Virgil, Sallust, Terence and Cicero.
Cassiodorus, the only writer who mentions Arusianus, refers to it by the term Quadriga.
